Letters Patent No. 94,167, dated August 24, 1869.

IMPR'OVEMENT IN HARVESTERS.

The Schedule referred to in these Letters Patent and making part of thesame.

Know all men by these presents:

That I, ALzInUs Bno'wn, of the city and county of Worcester, andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Mowing and Reaping-Machines; and I do hereby declarethat the following is a full, clear, and exact description, referencebeing bad to the accompanying drawings, forming a part of thisspecification, in which a Figure 1 represents a top or plan view of somuch of a mowing and reaping-machine is necessary to illustrate mypresent improvements j Figure 2 represents a section on line A B, fig.1; and

. Figure 3 represents a perspective view of a section of theconnecting-rod.

To enable those skilled in the art to which my invention belongs, tomake and use the said improvernents, I will describe the same more indetail.

My improvements relate to certain particular devices for retaining theconnecting-rod in place while the machine is in operatiomas will behereafter explained.

In the drawings- A is the shoe to which the heel-end B, of thefingerbeam 0, is fastened.-

The finger-beam is provided with slotted-finger, 1), through which thecutters E work, the cutters being fastened to thecutter-bar F, in theusual manner.

The shoe A, in this instance, is provided with carpieces a a, which arehinged between the ears 7) b b b of the hanger-iron G, which is tobefastened to the main frame in any proper manner.

H is the connecting-rod, only the end next to the cutter-bar beingshown, since that is sufficient to illustrate my present improvements.

'Rod II is provided with a wrist, c, which passes through a hole in theheel-end of the cutter-bar, whereby, when saidrod is operated by theusual crank-device, a rapid reciprocating motion is imparted to thecutter-bar and cutters.

Many devices have been employed for retaining the wrist or hooked end 0in place, the most common being a spring-key or pin, inserted in ahole'in the end of the wrist.

As such keys or pins are liable to work out, other devices have beentried, and, among the number, may be mentioned the casting 'of a flange,(I, on the upper side of shoe A, of sufiicient height to pass up abovethe end of the connecting-rod.

While this plan insures the retention of the rod in place, it involvesmuch friction, since a portiou of the described, I weld a steelprojection, e, on to the lower side oftl're-connectiug-rod, as indicatedin the drawings, whereby only avery narrow flange, (Z, is required toretain the connecting-rod in place, the pro ection e extending down pastthe upper edge of the flange, as

indicated in the drawings.

A guard-rod, I, is attached to the under side of the hanger-iron G, toprevent the cutter-bar and connecting-ro'd from falling down upon theground when the outer end of the finger-beam is raised up, which isnecessary, in order to swing the flange ll far enoughfi-onrtheprojection e to slip the wrist 0 out of the hole in thecutter-bar, when the latter is to be taken out for grinding the cuttersor for any other purpose.

The friction of the projection e is slight, while it is veryeflectual inretaining the connecting-rod in its proper position,- as beforeexplained.

The improvement, as shown, is more particularly applicable to themowing-machines, for which Letters Patent were granted tomyself,Kniflin, and Dodge, on the 17th day of November, 1863, but it may beapplied with good results on ll or nearly all of the other mowing andreaping-machines in use.

The projection e may be formed by upsetting or bending theconnecting-rod, or a small dog or finger may be secured in any propermanner tothe rod for the purpose;

Having described my ,jmprovements in mowing and reaming-machines, V

What I claim therein as new, and of my own invention, and desire tosecure by Letters Patent, is

1. A connecting-rod for mowing and reaping-machines, having a projectionc, substantially as and for the purpose set forth.

2. The combination with the connecting-rod, heelend of the cutter-bar,and the shoe which supports the heel of the finger-beam, of a projectione and flange d, substantially as and for the purpose set forth.

I 3. The combination with the connecting-rod H, cutter-bar 1*, flange d,and projection e, of the supporting or guard-rod I, substantially as andfor the purposes set forth.
